摘要:
An image sensor package includes a substrate and an image sensor mounted to the substrate. Bond pads of the image sensor are wirebonded to interior traces on the substrate by bond wires. An encapsulant encloses the bond wires, the encapsulant being formed of a first optically curable material that has been cured. A lid adhesive mounts a lid to the substrate, the lid adhesive being formed of a second optically curable material that has been cured. During fabrication, the first and second optically curable materials are cured rapidly without heating to form the encapsulant and the lid adhesive, respectively, thus minimizing the fabrication cost of the image sensor package.

A lead-frame method and assembly for interconnecting circuits within a circuit module allows a circuit module to be fabricated without a circuit board substrate. Integrated circuit dies are attached to a metal lead-frame assembly and the die interconnects are wire-bonded to interconnect points on the lead-frame assembly. An extension of the lead-frame assembly out of the circuit interconnect plane provides external electrical contacts for connection of the circuit module to a socket.

Semiconductor packages including at least one semiconductor chip and at least one electronic discrete device, such as a transistor, oscillator, optical sensor, resistor, capacitor, or inductor, are disclosed. The semiconductor chip and the discrete device are electrically coupled to each other, and are encapsulated within a protective encapsulant material. The semiconductor chip and the discrete device are disposed either in an aperture through the substrate or in a pocket of the substrate, thereby allowing for a thin package, even where the discrete device is taller (e.g., 1.5 to 5 times taller) than the semiconductor chip and/or substrate.

Semiconductor packages including at least two semiconductor dies are disclosed. A first die is mounted on a substrate, which may be a metallized laminate or a leadframe. A rigid support structure is mounted on the substrate over the first die. The support structure may be thermally coupled to the substrate, and also may be electrically coupled to the substrate. A second die is mounted on the support structure, which spaces the second die away from the first die. Encapsulant fills the volume within the support structure, including the vertical space between the pair of dies. In an alternative package embodiment, a heat spreader formed of a flexible metal sheet may be thermally coupled between the two stacked dies. The heat spreader transfers heat from the first and second dies to a heat sink of the substrate. The support structure and the heat spreader mitigate the transfer of heat between the first and second dies.

A method of forming an image sensor package includes wire bonding bond pads of an image sensor to interior traces on a substrate with bond wires. A first optically curable material is applied to enclose the bond wires. A second optically curable material is applied between a lid and the substrate. The first and second optically curable materials are cured through the lid with ultraviolet radiation. The first and second optically curable materials are cured rapidly without heating thus minimizing the fabrication cost of the image sensor package.

摘要:
A personalized circuit module package and method for packaging circuit modules provides graphical packaging for memory modules and other circuit modules. A removable housing is attached to a circuit module containing one or more integrated circuits bonded to a carrier and covered with an encapsulant. Graphics may be printed on the removable housing, or may be printed on an insert that is either inserted into a pocket within the removable housing, or is inserted between a removable housing having a window and the circuit module. Alternatively, the housing itself may be used to personalize the circuit module, by providing a colored or textured removable housing for the circuit module.
摘要:
An optical module includes a window having an interior, e.g., first, surface. The interior surface includes a central region and a peripheral region. A first electronic component is coupled to the peripheral region. The optical module further includes a substrate and an image sensor coupled to the substrate. The window is coupled to the substrate such that the image sensor is aligned with the central region of the window.
